I have long been a fan of these series & usually carry a full set of DVDs in the van for when we have no reception.
I recall that in my last 'Technical' position as OIC of a large Technical Operations group, circa 1986, one of my Managers RIP (I consider him to have been at that time, the equivalent to Bernard) suggested that our organisation was very similar to this, with my 2IC/3IC, an extremely intelligent and capable guy with a Bachelors Degree in Computer Science and an MBA, to be the equivalent of Sir Humphery.
On reflection, I think that he was close to the truth.
Thanks for sharing .. I'll get the DVDS out to rewatch for the umpteenth time.
